摘要：
An original waveguide located in a woodpile (layer-by-layer) crystal is presented in this paper. Its geometrical sizes, shape and location have been optimized in order to maximize its bandwidth and the matching between this guide and the Input/Ouput feeding WR waveguides. The 3D Electromagnetic Band Gap (EBG) crystal has been designed, optimized and manufactured in one monolithic piece with Zirconia (epsilon r=31.2 at 30GHz) by the 31) ceramic stereolithography process. It experimentally exhibits a large complete bandgap superior to 20% and the waveguide located in such woodpile provides a measured 20% bandwidth around 26GRz while keeping a return loss inferior to -10dB.
